Engineered for architectural environments exposed to high humidity and moisture fluctuations, this core utilizes treated wood fibers and moisture-resistant polymer resins, hot-pressed under controlled thermal parameters. It prevents moisture uptake, dimensional swelling, and structural degradation, serving as a stable substrate for wood veneer, HPL (High-Pressure Laminate), and paint finishes.
Key Features
Low Thickness Swell: Controlled resin-to-fiber ratio limits water absorption, restricting thickness swell to under 3.5% after 24-hour immersion testing.
Biological Resistance: Treated with anti-fungal additives to resist mold and rot in enclosed, humid spaces.
Structural Stability: Cross-directional fiber distribution maintains flat tolerances, preventing warping or door leaf twisting under differential climate stress.
Machinability: Uniform density profile allows clean edge routing, mortising for hardware, and secure hinge screw retention meeting commercial duty requirements.

Applications
Healthcare Facilities: Patient rooms, surgical prep areas, and washrooms requiring frequent sanitization and washdown.
Hospitality: Hotel guest room entry and bathroom doors subject to steam and temperature shifts.
Commercial Restrooms: Office buildings, airports, and sports complexes with high ambient humidity.
Marine & Coastal Structures: Interior cabin doors and bulkhead panels exposed to salt air and moisture.
Customization Options
Dimensions: Cut-to-size panels matched to specific finished door frame dimensions to minimize job-site waste.
Fire Ratings: Integrated intumescent edge banding options meeting 20-minute, 45-minute, or 60-minute fire ratings (UL 10C certified formulations).
Tubular Core Variations: Available in solid core or engineered tubular configurations to balance acoustic insulation and weight requirements.
Face Preparation: Calibrated sanded surfaces ready for direct veneer pressing or HPL lamination.
Quality & Supply
Rigorous Quality Control: Every production lot undergoes destructive internal bond testing, moisture content checks, and 24-hour water immersion verification in our factory laboratory prior to packaging.
Certified Standards: Manufacturing facilities operate under ISO 9001 Quality Management Systems. Products comply with international environmental and safety standards including FSC Chain of Custody, CARB Phase 2, and CE certification for European markets.
Logistics & Supply Chain: Standard production lead times run 15 to 25 days. Cores are strapped, edge-protected, and shrink-wrapped on heavy-duty wooden pallets designed to withstand international containerized or flatbed ocean freight.
FAQ
Q: Can this door core be machined using standard woodworking tools?
A: Yes. The homogenous density allows standard carbide-tipped tooling for cutting, drilling, and mortising without excessive edge chipping.
Q: What is the maximum available panel size for custom orders?
A: Standard widths are up to 1220mm (4 feet) and lengths up to 3050mm (10 feet). Non-standard dimensions require minimum order quantity (MOQ) verification.
Q: How does this core perform under HPL (High-Pressure Laminate) pressing?
A: The calibrated, sanded surface provides high flatness tolerance, ensuring bubble-free adhesion using cold press or hot press PVA/PU adhesives.
Q: Are test reports and compliance certificates available for project submittals?
A: Yes. Certified physical property test reports, UL fire-rating documents, and CARB/FSC certificates are provided upon inquiry for architectural submittal packages.
